Description

TELEPHONE DIALING The present invention relates to telephone dialing and particularly, although not exclusively, to telephone dialing in a radio mobile telephone.

In general, radio mobile telephones include hand portable telephones and radio telephones for installing in vehicles. Radio mobile telephones usually perform radio communication with a cell site, which is wire-connected to an exchange station. Therefore, a radio mobile telephone can perform both radio communication with any other radio telephone and wire communication with a general telephone.

In the typical radio mobile telephone structure shown in Figure 1 of the accompanying diagrammatic drawings, a control unit 111 controls overall operation of the radio mobile telephone. A first memory 112 may comprise an electrically erasable and programmable ROM (EEPROM), and stores program and initial service data. A second memory 113 may comprise a RAM, and temporarily stores data generated during operation of the radio mobile telephone.

A key inputting unit 114 generates key data for executing various modes and dialing operation of the radio mobile telephone, thereby to output generated key data to the control unit 111. A logic unit 115 transmits/receives data for controlling the control unit 111 and operations of the radio mobile telephone. Also, the logic unit 115 outputs control data for controlling operation of each unit of the radio mobile telephone. A data processing unit 116, which communicates data with the control unit 111, signal-processes received data RXD output from an RF receiving unit 120, thereby to apply the processed result to the control unit 111, and signal-processes transmitting data TXD output from the control unit 111, thereby to output the processed result to an RF transmitting unit 121. In this case, the data processing unit 116 may use a digital signal processor.

A duplexer 122 is connected to an antenna, thereby to separate the receiving RF signal and the transmitting RF signal. The RF receiving unit 120, which is connected to the duplexer 122, FM demodulates the received RF signal.

A received audio signal RXA and received data RXD output from the RF receiving unit 120 are respectively output to an audio receiving unit 117 and the data processing unit 116. The audio receiving unit 117 receives an audio signal output from the RF receiving unit 120, thereby to regenerate the audio signal. An audio transmitting unit 118 receives an audio signal and processes it. The RF transmitting unit 121 receives a transmitted audio signal TXA output from the audio transmitting unit 118 and transmitted data TXD output from the data processing unit 116, thereby to modulate the input TXA and TXD into a transmission form, and then outputs the modulated signal to the duplexer 122.A frequency synthesizer 119 generates a synthesized frequency for a reception channel of the RF receiving unit 120 and a transmission channel of the RF transmitting unit 121 according to control data of the logic unit 115.

Referring to Figure 2 of the accompanying diagrammatic drawings, which shows a flowchart illustrating conventional calling operations of the radio mobile telephone constructed as described above, the control unit 111 scans the key inputting unit 114 to detect whether or not key data is input. When a key signal is generated by the key inputting unit 114, the control unit 111 senses generation of the key signal and analyzes the,input key signal (step 211). If the input key signal is a numeric key, the control unit 111 senses that a dial key data is input (step 213) and stores input key data in the second memory 113 (step 215), and then, the control unit 111 returns to step 211.While repeating the operation as mentioned above, the control unit 111 receives dial key data corresponding to the telephone number of a called party (i.e. subscriber) and stores received key data in the second memory 113. In step 211, if key data input is a "send" key data, the control unit 111 senses that the "send" key is input (step 217) and then outputs data stored in the second memory 113 to data processing unit 116. And then, the data processing unit 116 outputs the called party's telephone number data to the RF transmitting unit 121, and the RF transmitting unit 121 modulates telephone number data to the RF signal, thereby to output the RF signal. After that, the control unit 111 proceeds to step 221, thereby to execute a communication mode, and if the called party responds, a speech path is formed.

In the conventional radio mobile telephone, in order to completely perform the dialing operation, the "send" key should be pressed after the called party's telephone number is dialed.

Preferred embodiments of the present invention aim to provide automatic dialing operation by inputting only a called subscriber's telephone number in a radio mobile telephone.

According to one aspect of the present invention, there is provided a telephone dialing method, comprising the steps of: a. receiving key data from a key input means; b. detecting whether such key data is dial key data; c. storing such dial key data; and d. automatically dialing a telephone number corresponding to such stored dial key data, at the expiry of a predetermined time period.

Said predetermined time period may be started following the receipt of an item of dial key data, and is restarted following the receipt of a next item of dial key data before the expiry of the predetermined time period.

Said predetermined time period may be started following the receipt of an item of dial key data, and continue until its expiry, irrespective of the receipt of next items of dial key data.

Said predetermined time period may beis first started only following the receipt of a predetermined number of items of dial key data.

Said predetermined time period may be started following the receipt of a first item of dial key data.

A telephone dialing method as above may include the step of analysing input key data to distinguish between general dial key data and abbreviated dial key data and, in the event that abbreviated dial key data is detected, automatically dialing a stored telephone number corresponding to such abbreviated dial key data, at the expiry of said predetermined time period.

A telephone dialing method as above may include the step of analysing input key data to distinguish between dial key data and send key data and, in the event that send key data is detected, dialing a telephone number corresponding to stored dial key data, without waiting for the expiry of said predetermined time period.

According to another aspect of the present invention, there is provided a telephone adapted to perform a method according to any of the preceding aspects of the invention, the telephone comprising: a. key input means for a user to input said key data; b. detecting means for detecting whether such key data is dial key data; c. storing means for storing such dial key data; d. timer means for timing said predetermined time period; and e. automatic dialing means for automatically dialing a telephone number corresponding to such stored dial key data, at the expiry of said predetermined time period.

In any of the preceding aspects of the invention, the telephone may be a radio mobile telephone.

For a better understanding of the invention, and to show how embodiments of the same may be carried into effect, reference will now be made, by way of example, to Figures 1, 3 and 4 of the accompanying diagrammatic drawings, in which: Figure 3 is a flowchart illustrating the dialing operation of one example of a radio mobile telephone in accordance with a first embodiment of the present invention; and Figure 4 is a flowchart illustrating the dialing operation of another example of a radio mobile telephone in accordance with a second embodiment of the present invention.

The following embodiments of the invention will be described with reference to a radio mobile telephone which has a general structure as shown in Figure 1. However, in the following embodiments of the invention, the control unit 111 provides various means for performing different functions.

In Figure 3, the flowchart illustrates automatic dialing operations in accordance with the first embodiment of the present invention. The first embodiment is adapted to perform a method which comprises the steps of: detecting whether or not key data is input, and analyzing input key data upon input of key data; storing key data when the result analyzed in the analyzing step is general dial key data, returning to the detecting step when the number of input key data is less than a designated number, and standing-by for timing an input time of key data when the number of input key data is the designated number or more; repeating the steps as mentioned above by returning to the analyzing step, when next key data is input within a designated period of time in the standing-by step, and automatically dialing a telephone number in accordance with stored key data, when next key data is not input during the designated period of time; storing abbreviated dial key data when the result analyzed in the analyzing step is abbreviated dial key data, repeating the steps as mentioned above by returning the analyzing step when next key data is input within the designated period of time, and automatically dialing a telephone number in accordance with key data being stored when next key data is not input during the designated period of time; and automatically dialing a telephone number in accordance with stored data when the result analyzed in the analyzing step is "send" key data.

In Figure 3, the control unit 111 scans the key inputting unit 114, thereby to detect whether or not key data is input. If key data is received from the key inputting unit 114, the control unit 111 senses input of key data (step 311) thereby to analyze input key data. At this point, if an analyzed result is key data for executing a general dial mode, the control unit 111 senses input of general dial key data (step 313), and stores input data in a dial buffer of the second memory 113 (step 315). In the general dial mode, the telephone number is input by using the numeric key, and the control unit 111 repeats the steps as previously mentioned, thereby to store numeric key data of the input telephone number in the second memory 113.

After storing numeric key data of the input telephone number in the dial buffer of the second memory 113, the control unit 111 detects whether the number of digits of the telephone number stored in the dial buffer is a designated number K or more (step 317). Existing telephone communication patterns can be largely classified into local area calls, long distance calls, international calls and so on. Accordingly, there are at least three types of telephone number formulae. First, for a local area call, the telephone number has to contain a block number and a subscriber's number. Second, for a long distance call, the telephone number has to contain an area code, a block number and a subscriber's number. Finally, for an international call, the telephone number has to contain a country code, an area code, a block number and a subscriber's number.Therefore, the designated number K should be at least the number of digits of the telephone number required for a local area call.

The telephone number formula for dialing a radio mobile telephone is usually different from the general telephone number formula. For example, in the case of dialing a radio portable telephone by using a radio mobile telephone, a caller has to dial a specific number (e.g.

012) that is an identification number of the radio mobile telephone, together with the telephone number. In the case of calling a general telephone by using the radio mobile telephone, the caller has to dial the area code of the general telephone, together with the telephone number.

But, in the case where the radio mobile telephone and the called party's telephone are located in the same area to each other, the caller using the radio mobile telephone doesn't have to dial the area code. (This can differ from country to country).

Accordingly, if, in step 317, the number of digits of the telephone number stored in the dial buffer is the designated number K or more, the control unit 111 measures the time elapsed from input of present key data to input of next key data by performing the steps 319 and 321.

Thereby, if no more telephone number is input within a given period of time N after the minimum number K of telephone number digits has been input, the control unit 111 determines that input of the telephone number is ended. Here, the given period of time N is designated by 1.5 second (for example). Accordingly, in the case that the number of digits of the telephone number being stored in the dial buffer of the second memory 112 is the designated number K or more, if input of next key data is sensed within the 1.5 second in steps 319 -321, the control unit 111 returns to step 313.On the other hand, contrarily, if next key data is not input until the 1.5 second has lapsed in steps 319-321, the control unit 111 determines that input of the telephone number is ended, and then proceeds to step 323, thereby to output telephone number data being stored in the dial buffer of the second memory 113 to the data processing unit 116. Then, the data processing unit 116 outputs input data to the RF transmitting unit 121, and the RF transmitting unit 121 performs an automatic dialing operation by converting the telephone number into the RF signal, thereby to transmit the RF signal. Then the control unit 111 proceeds to step 325, thereby to perform a communication mode.

The radio mobile telephone can perform a dialing operation by executing abbreviated dial mode, as well as the general dial mode mentioned above. Here, the abbreviated dial mode is executed by using an abbreviated dial table in the first memory 112, where the telephone numbers for an abbreviated dialing are previously stored. Key data input in the abbreviated dial mode generally consists of numeric key data of one or two digits. Accordingly, if numeric key data for the abbreviated dialing is generated after a user designates the abbreviated dial mode, the control unit 111 senses generation of the numeric key data (step 327), and stores received abbreviated dial numeric key data in the dial buffer of the second memory 113. Then, the control unit 111 proceeds to steps 319 and 321, thereby to check the time elapsed from input of present key data to input of next key data. If key data is not received until 1.5 second has lapsed in steps 319-321 as previously described, the control unit 111 determines that input of the telephone number is ended. Accordingly, the control unit 111 proceeds to step 323, thereby to check numeric key data stored in the dial buffer of the second memory 113. The control unit 111 then accesses the telephone number stored in an area corresponding to the numeric key on the abbreviated dial table of the first memory 112, thereby automatically dialing the telephone number.

The key inputting unit 114 of the radio mobile telephone separately includes a "send" key for completing a dialing operation in a conventional manner, as described above.

Accordingly, the caller completes the dialing operation by pressing the "send" key after dialing the telephone number. In this case, the control unit 111 senses that the "send" key is pressed in step 329, and dials the telephone number being stored in step 331.

In Figure 4, the flowchart illustrates the automatic dialing operation of a radio mobile telephone in accordance with the second embodiment of the present invention. The dialing method in accordance with the second embodiment comprises the steps of: detecting whether or not key data is input, and analyzing input key data upon input of key data; storing general dial key data when the result analyzed in the analyzing step is general dial key data, returning to the detecting step when a number of input key data is less than a designated number, and standing-by for measuring a generating period of present key data when the number of input key data is the designated number or more; repeating the steps as mentioned above by returning to the analyzing step, when a generating period of key data is within the designated period of time in the standing by step, and automatically dialing the telephone number in accordance with the stored key data, when the generating period of key data is over the designated period of time; storing abbreviated dial key data when the result analyzed in the analyzing step is abbreviated dial key data, returning to the inputting step when a generating period of present key data is within the designated period of time, and automatically dialing the telephone numbers in accordance with stored key data when the generating period of present key data is over the designated period of time; and automatically dialing the telephone number in accordance with stored key data, when "send" key data is input in the analyzing step.

In Figure 4, the control unit 111 scans the key inputting unit 114, thereby to detect whether or not key data is input. If key data is received from the key inputting unit 114, the control unit 111 senses input of key data (step 411) thereby to analyze input key data (step 413).

If the result analyzed in the analyzing step is key data for performing the general dial mode, the control unit 111 proceeds to step 415, thereby to store input key data in the dial buffer of the second memory 113. In the general dial mode, the telephone number is input by using the numeric keys, and the control unit 111 repeats the steps as described above, thereby to receive numeric key data of the telephone number in the second memory 113.

After storing input numeric key data of the telephone number in the dial buffer of the second memory 113, the control unit 111 detects whether the number of digits of the telephone number stored in the dial buffer is a designated number K or more (step 417).

Accordingly, if the number of digits of the telephone number stored in the dial buffer is the designated number K or more in step 417, the control unit 111 detect whether the generating period of present key data is over a designated period of time M, i.e. if the caller continues to press a final key of the telephone number in order to dial until the designated period of time M has lapsed, the control unit 111 determines input key data as the final telephone number. Here, the designated period of time M is designated by 1.2 second.Accordingly, if the generating period of key data, when the number of telephone number data stored in the dial buffer is the designated number K or more, is over 1.2 second (i.e. the designated period of time), the control unit 111 determines input key data as the final telephone number in step 419, and proceeds to step 423, thereby to output telephone number data being stored in the dial buffer to the data processing unit 116. Then, the data processing unit 116 outputs input data to the RF transmitting unit 121, and the RF transmitting unit 121 converts the telephone number into the RF signal, thereby to output the RF signal, thereby performing the automatic dialing operation. Then the control unit 111 proceeds to step 425, thereby to execute the communication mode.

Furthermore, if numeric key data for abbreviated dialing is generated after the caller designates the abbreviated dial mode, the control unit 111 senses generation of abbreviated key data in steps 427 and 428, and stores received abbreviated dial key data in the dial buffer of the second memory 113. Then, the control unit 111 proceeds to step 419, thereby to detect whether the generation period of key data is over the designated period of time M. If the input period of key data exceeds the designated period of time M, the control unit 111 determines input key data as the final telephone number.

Then, in step 423, the control unit 111 accesses the telephone number stored in the area corresponding to the numeric key on the abbreviated dial table of the first memory 112, thereby to automatically dial the accessed telephone number, after checking numeric key data being stored in the dial buffer of the second memory 113.

As described previously, the key inputting unit 114 of the radio mobile telephone separately includes the "send" key for performing a conventional dialing operation.

Accordingly, the caller completes the dialing operation by using the "send" key after dialing the telephone number.

In this case, if the control unit 111 senses that the "send" key is pressed in step 429, it dials the telephone number being stored in step 431.

When a user makes a call by using the radio mobile telephone as described above, if next key data is not input or input of key data is continued beyond the designated period of time, the radio mobile telephone determines that input of the telephone number is ended.

In this case, the radio mobile telephone automatically dials the telephone number being stored, thereby easily performing the dialing operation.
